What is a WPC/SPC/PVC Crushing and Pulverizing System?

The WPC/SPC/PVC Crushing and Pulverizing System is an automated production line specifically designed for recycling edge trims and defective products from WPC (wood-plastic composite), SPC (stone-plastic composite), and PVC materials. Through crushing and grinding processes, waste materials are converted into reusable fine powder, enabling efficient resource recycling.

WPC/SPC/PVC crushing and grinding system typically consists of modules such as an automatic elevating conveyor, crusher, grinder, and pulse dust collector, and supports customized configurations based on output and automation requirements.

The Working Process of  WPC/SPC/PVC Crushing and Grinding System:

● Crushing Stage: Large pieces of WPC scrap are initially crushed into small particles using a crusher.

● Grinding Stage: The particles are fed into a grinding mill via an iron-removing conveyor, where they are ground into fine powder by the action of moving and stationary blades.

● Screening and Collection: The powder is driven into a vibrating screen by a fan. Qualified powder is collected, while unqualified material is returned to the grinding chamber for further crushing. Particle size description: The higher the mesh number, the finer the powder. 20 mesh ≈ 850μm, 150 mesh ≈ 100μm, suitable for recycling granulation; 200 mesh and above (≤75μm) suitable for high-value-added modified materials.

● Environmental Protection: Equipped with a pulse dust collector to effectively control dust emissions and meet environmental standards. Dust Collection System: Due to the high dust concentration during the WPC grinding process, a pulse dust collector is recommended as standard equipment, complying with GB 16297-1996 Air Pollutant Emission Standards.

Key Parameters and Performance Characteristics:

The fineness adjustment range of the WPC/SPC/PVC crushing and pulverizing system is 20-40 mesh. This parameter directly affects the surface texture and physical properties of wood-plastic composite flooring. If the fineness is too high, it may lead to poor raw material flowability; if it is too low, it will affect the density of the finished product. By changing the screen mesh with different aperture sizes, different process requirements can be flexibly met.

The equipment adopts a cast iron body design with a weight of 1680kg-3500kg, which effectively reduces vibration and noise during operation and improves equipment stability. Actual test data shows that under continuous operation for 8 hours, the equipment temperature rise is controlled within 15℃, meeting the durability standards for industrial-grade equipment.

Technological Advantages and Industry Adaptability:

Compared to general-purpose crushing and grinding systems, this system has three major advantages in wood-plastic composite material processing:

● The matching relationship between the cutter roller speed and torque has been optimized to address the shear strength characteristics of wood-plastic composites, effectively reducing ineffective energy consumption.

● The screen structure has been improved with a trapezoidal hole design, significantly reducing the risk of material blockage.

● An integrated dust removal system utilizes a negative pressure suction device to suppress dust overflow, meeting environmentally friendly production standards. These features enable it to exhibit higher overall efficiency in SPC/WPC flooring production lines, making it particularly suitable for large-scale enterprises with an annual output of over 500,000 square meters.
